Application filed April 15, 1915. Serial No. 21,480.

I! '0 all whom it mag concern:

Be it known that I, ALEXANDER L. Somme, a citizen of the United States, and resident of Hillsboro, Montgomery county, Illinois, have invented certain new and useful Improvements in Glass-Furnaces, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in glass furnaces, and is especially directed to the means for controlling the delivery ofv glass from the furnace.

One object of my improvements is to facilitate and more readily control the delivery of molten glass from a furnace, and a further object of my invention is to construct an improved means for attaching a boot or delivery spout to the furnace proper whereby the level of the boot may be adjusted in order to control the fiow of glass therethrough, as well as to provide for a vertical movement of the outer end of the boot at times when a part fof a glass forming machine has engaged or caught under the same whereby to free the machine from the boot. With these objects in view my invention consists in the novel arrangement and construction of parts. hereinafter fully described, pointed out in my claims and illustrated by the accompanying drawings, in which- Figure 115 a front elevation of an apparatus constructed according to my invention;

Fig. 2 is a side elevation of the-device as applied to a glass furnace;

Fig. 3 is a sectional elevation through the boot or delivery spout and part of the glass furnace; and

Fig. 4 is a detail perspective of a portion of the plug adjusting means.

Referring by numerals to theaccompanying drawings:

5 designates the glass furnace having in its side wall a delivery opening 6. Secured to the wall of the furnace on each side of the opening 6 is a metallic post 7, connected adjacent their uppermost ends by an angle iron 8 and connected at points just below the opening 6 by a metallic bracket 9. This bracket constitutes a support for the inner- .aifords ample access most end of a metallic base or support 10 whlch comprises a bottom and side walls arising from the front end and side margins, but not from the rear end margin.

At its upper margins on each side of the base near its outer end there is an integral boss 11 and extending from these two bosses to the angle iron 8, at the upper ends of the metallic posts, are the suspension rods 12, having intermediate their ends means for varying their lengths, such as the turn buckles 13.

Within the walls of the metallic base, I place the trough shaped body 14 of the boot or delivery spout, which extends to the wall of the furnace registering with the opening 6, whereat a glass tight joint is made. Near its outer end and through its bottom the boot is rovided with an opening 15, into which t ere is inserted a bushing 16 forming the discharge orifice of the furnace. An opening 17 through the metallic base of much greater diameter than the bushing to the boot body for the purpose of removing bushings, as well as the flow of glass through the base.

Supported on the trough-shaped boot body with its lowermost ends within the walls ofthe metallic base is a hood 18, whose inner end abuts the wall of the furnace around the opening 6. The hood extends forwardly from the furnace to a point cen trally over the bushing 16.

The hood end 19 forms a continuation of from the point centrally to the outer end of the separable from the body the hood proper over the bushin boot, and is ma e to permit of easy access controlling the flow of bushing.

14 indicates a applied to the metallic base 10 and braces the hood section 19.

This glass flow controlling means comprises primarily a plug 20 and like the boot and hood is formed of material, such as fire clay or the like, capable of withstanding great heat.

It is apparent from th1s showing that while the discharge opening is removed from the furnace proper, the boot and hood being in open communication with the furskeleton frame which is and replacing nace, the glass in the boot, even at its end remote from the furnace will be maintained at about the temperature of the furnace.

Arising from the bosses at the sides of the metallic base are the standards 21, which support at some considerable elevation above the boot a bar 22, which has depending from its one end a bracket 23 bifurcated at its lowermost extremity to straddle the annularly grooved hub of a hand Wheel 24;. To one oi? the tines otthis bracket there is pivotally secured a plate 25, which has at its free end a notch 26 arranged to coact with a pin in the opposite tine to hold the plate in position to prevent the hub of the hand wheel from withdrawal from the bracket. I I

Arising from the bar 22 opposite its end carrying the bracket 23 is a vertically disposed bar 27, perforated at intervals for adjustably securing thereto a lever 28, from which the plug is suspended by a link 29. Connected, with the lever 28 at its outer freeend is a threaded bar 30 which extends through the hand wheel 2%. By

manipulating this hand wheel l obtain anextremely fine'plug adjustment with a minimum of ei iort.

it is apparent from this showing that the discharge orifice is arranged removed from the vertical wall'of the furnace, whereby to malre possible the positioning of a glass forming machine beneath the orifice to receive-glass flowing by gravity from the :turnace. Thearrangement and capacity 01 the'boot or delivery spout being relatively larger than the normal capacity of the discharge opening and the hood forming with the boot a chamber in open communication with the'furnace to receive heat from the furnace makes possible the continuous flow oi glass from the furnace through a discharge orifice removed laterally from the wahl or? the furnace properz.

- In the provision of the boot or delivery spout supportin means at its inner end, adjustable suspending means at its outer end, I may obtain the leveling of the ,acaear hoot or delivery sprout in order to partially control the iiow of glass therethrough as well as the obtaining of a boot support which will permit the lifting bodily of the outer end of the boot so that when a forming machine is brought thereunder and a part thereoi is engaged and caught in. the boot, the boot may be elevated to free the forming machine.

Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent therefor, is

1. An apparatus for delivering glass from a glass furnace comprising, in combination with the glass furnace having a discharge opening, a pair or" metallic supports positioned adjacent to said opening, a bracket secured to said supports, a skeleton metallic base provided with bosses having one of its ends mounted on said bracket, a sectional hood provided with an opening mounted on said base, a skeleton trams secured to said base and embracing the sectional hood, an adjustable support extending from the bosses to the supports, and an adjustable plug mounted in the sectional hood.

2. An apparatus for delivering glass from a glass furnace comprising, in combination with the glass furnace having a discharge opening, a pair of metallic vertical supports positioned adjacent to said opening, a bracket secured to said supports below the opening, a skeleton metallic base provided with bosses, having one of its ends mounted on said bracket, a sectional fire-proof hood with an opening mounted on said base, an adjustable support extending from the bosses to the vertical supports and an adjustable plug mounted in the sectional hood.

in testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
